To all whom it may concern States, residing at Akron, in the county of Summit and State of Ohio, have invented -new and .useful Improvements in .Waterproofing Compositions, of which in is a specification.

's invention relates to a waterproofing composition and hasparticular relation to a waterproofing composition which is adapted to make cloth, leather, paper or the'hke water repellent.

-.The object of the invention is to" provide animproved waterproofing com osition which will be transparent and which will not injure orstain the article to which it is ap lied. nother object is to provide a composition of theclass above described whichwill preserve the fabric or other substance to which it may be applied and which will last in definitely andqmayibe easily and economir' cally manufactured.

A still further object is to provide a waterproofing composition with which cloth, leather or other substances may be treated -without closing the pores or. interstices therein and which when it is so'treated will not absorb water or other liquid by capillary attraction. v

With the above objects and others in view,-

, and 'treatment of elements and the compounding of ingredients hereinafter described; it belng understood that changes,

variations and modifications may be resorted to which come within the s irit of the in vention, and the scope .of't

Broadly, a Waterproofing compoundmanw factured in accordance with this invention the follow- Specification of Letters Patent. Application filed November 22, 19:9. wSerial No. 339,996.

Patented Dec; a, 1921.

consists of the following in redientsfPan aflin, gasolene, benzol, unvu canized rubber and peppermintoil. I prefer to mix the ingredients in the following proportions: One pound paraffin, one pint high test gasolene, six pints benzol; one ounce rubber and one dram peppermint oil. The paraflin is first melted, preferably by'steam, and tothe melted parafiin the gasolene is added; therubber 18 added to the benzol which is churned until the rubber is thoroughly dis-- solved; to this mixture the paraffin and gasolene are added, the oil of peppermint is thenadded and the mixture is well agitated.

' While'rubber in any dissolvable formmay be used, we. prefer to use washed Para rub- *ber, or other'rubber, which will not cloud the mixture and discolor the article on which the composition is used. The mixture of the above named ingredients as above set forth results in a clear, .transparent liquid which in use is applied directly to the article to be used. The oil of peppermint maybe omitted as it'is not essential to the composition claimed. I

Having thus described ourinvention what desire to secure by we claimas new and Letters-Patent is:-

1.- A waterproofing composition consisting of. parafiin, gasolene, benzol and rubber sub stantially as herein described.

2. That method of manufacturing a waterproofing composition comprising the following steps: first, melting paraffin and adding gasolene to the melted parafiin; second. the

dissolving of rubber in benzol; third, adde claims here-- ing the pa'raflin and gasolene to the benzol and rubber substantially as herein set'forth.

a In testimony whereof we have hereunto set our hands. OTTO H. BRAUSER.
